* Use #line directives in generated C++ code for lambdas The #line directive in gcc is meant specifically for pieces of imported code included in generated code, exactly what happens with lambdas in the yaml files: https://gcc.gnu.org/onlinedocs/cpp/Line-Control.html With this change, if I add the following at line 165 of kithen.yaml: - lambda: undefined_var == 5; then "$ esphome kitchen.yaml compile" shows the following: INFO Reading configuration kitchen.yaml... INFO Generating C++ source... INFO Compiling app... INFO Running: platformio run -d kitchen <...> Compiling .pioenvs/kitchen/src/main.cpp.o kitchen.yaml: In lambda function: kitchen.yaml:165:7: error: 'undefined_var' was not declared in this scope *** [.pioenvs/kitchen/src/main.cpp.o] Error 1 == [FAILED] Took 2.37 seconds == * Silence gcc warning on multiline macros in lambdas When the \ is used at the end of the C++ source in a lambda (line continuation, often used in preprocessor macros), esphome will copy that into main.cpp once as code and once as a // commment. gcc will complain about the multiline commment: Compiling .pioenvs/kitchen/src/main.cpp.o kitchen.yaml:640:3: warning: multi-line comment [-Wcomment] Try to replace the \ with a "<cont>" for lack of a better idea. |
